See this old post on Breaking Bad.Unlike Chris Kyle, who claimed his PTSD came from the inability to save more service members, most of the damage to my mental health was what I call “moral injury,” which is becoming a popular term in many veteran circles.As a sniper I was not usually the victim of a traumatic event, but the perpetrator of violence and death. My actions in combat would have been more acceptable to me if I could cloak myself in the belief that the whole mission was for a greater good. Instead, I watched as the purpose of the mission slowly unraveled.I served in Iraq from 2004 to 2005. During that time, we started to realize there were no weapons of mass destruction, the 9/11 commission report determined that Iraq was not involved in the terrorist attacks on the World Trade Center, false sovereignty was given to Iraq by Paul Bremer, the atrocities at Abu Ghraib were exposed, and the Battle of Fallujah was waged.The destruction I took part in suddenly intersected with news that our reasons for waging war were untrue. The despicable conduct of those at Abu Ghraib was made more unforgivable by the honorable interactions I had with Iraqi civilians, and, together, it fueled the post-traumatic stress I struggle with today.My war was completely different than Chris Kyle’s war. That doesn’t mean his war is wrong, and mine was right. But it does mean that no one experience is definitive.
